01 / CalculatorMetal Weight CalculatorPick a shape, enter the dimensions in millimetres or inches, choose the grade. The weight comes from the section geometry and the grade density, in the same engine that prices the enquiry.Explore tool →02 / Engineering indexCoil Weight CalculatorEnter the coil outside diameter, inside diameter and width in millimetres and choose the grade. The weight comes from the ring volume and the grade density; a second calculation estimates the number of wraps from the strip thickness.Explore tool →03 / Engineering indexCoil Length CalculatorEnter the coil weight in kilograms, the strip width and thickness in millimetres and choose the grade. The length comes from the weight divided by the strip's weight per metre; a second calculation returns the outside diameter that weight builds on a known bore.Explore tool →04 / Engineering indexPREN CalculatorEnter the chromium, molybdenum and nitrogen content of the grade in weight percent. The pitting resistance equivalent number is a comparison index between stainless grades, computed with the 16 N form used for duplex and austenitic steels.Explore tool →05 / Engineering indexPerforated Sheet Open Area CalculatorChoose the hole pattern, enter the hole size and pitch in millimetres, and read the open area as a percentage. A fourth calculation turns a solid sheet weight and an open area into the net weight of the perforated sheet.Explore tool →06 / Engineering indexMetal Surface Area CalculatorChoose the geometry, enter the dimensions in millimetres, and read the surface area in square metres. Surface area is what a PVD, polishing, painting or anodising quotation is priced on, so this is the figure to bring to a finishing enquiry.Explore tool →07 / Engineering indexCarbon Equivalent CalculatorEnter the steel composition in weight percent from the mill certificate. The carbon equivalent estimates how prone the steel is to hardening and cold cracking at a weld, and is the number a welding engineer reads before deciding on preheat.Explore tool →08 / Engineering indexThermal Expansion CalculatorEnter the expansion coefficient from the grade datasheet, the length at the starting temperature and the temperature change. The engine returns the change in length in millimetres — positive for heating, negative for cooling.Explore tool →09 / ConverterUnit ConverterPick the quantity, the unit you have and the unit you need, then type the value. The converter runs the constants from our calculation workbook, marks the exact ones, and offers an enquiry with the converted figure already in it.Explore tool →10 / ConverterPressure ConverterChoose the unit you have and the unit you need, then type the value. The converter runs the workbook constants between megapascals, bar and psi, and offers an enquiry with the converted figure already in it.Explore tool →11 / ConverterDensity ConverterType a density in grams per cubic centimetre to read it in kilograms per cubic metre, or the reverse. The factor is exactly one thousand, and the result offers an enquiry with the converted figure already in it.Explore tool →12 / ConverterTemperature ConverterChoose the scale you have and the scale you need, then type the temperature. The converter runs the workbook formulas between Celsius, Fahrenheit and kelvin — the only conversions on the site that add rather than multiply.Explore tool →13 / Grade finderASTM / EN Grade Equivalent FinderType a grade or designation and read the equivalence records the material database holds for it — the designation systems, how close the match is, and what differs. Equivalents are a technical reference, not a substitution instruction.Explore tool →

Weight Calculator
One calculator for every material — choose stainless, aluminium, carbon steel, copper, brass or a specialty alloy, pick the shape and enter the dimensions.
Weight = Density × Cross-section × Length
